DESCRIPTION
The DS1065 is a fixed frequency oscillator requiring no external components for operation. Numerous
operating frequencies are possible in the range of approximately 30 kHz to 100 MHz through the use of
an on-chip programmable prescaler and divider.
The DS1065 features a master oscillator followed by a prescaler and then a programmable divider. The
prescaler and programmable divider are user-programmable with the desired values being stored in
nonvolatile memory. This allows the user to buy an off the shelf component and program it on site prior
to board production. Design changes can be accommodated easily by simply programming different
values into the device (or reprogramming previously programmed devices). The DS1065 is shipped from
the factory configured for half the maximum operating frequency. Contact the factory for specially
programmed devices.
The DS1065 features a dual-purpose Input/Output pin. If the device is powered up in Program mode this
pin can be used to input serial data to the on-chip registers. After a write command this data is stored in
nonvolatile memory. When the chip is subsequently powered up in operating mode these values are
automatically restored to the on-chip registers and the Input/Output pin becomes the oscillator output.
The DS1065 is available in TO-92 (3 LEAD) package, allowing the generation of a clock signal easily,
economically and using minimal board area.
